Abstract (en)
[origin: US2022190950A1] The disclosure relates to an apparatus including a receiver configured to process a radio frequency (RF) signal to generate a baseband signal; a radio frequency (RF) jammer detector configured to generate a signal indicative of whether an RF jammer is present at an input of the receiver; and a receiver bias circuit configured to generate a supply voltage for the receiver based on the RF jammer indication signal. In another aspect, the apparatus includes constant gain bias circuit to maintain the gain of the receiver constant in response to changes in the supply voltage. In other aspects, the receiver bias circuit may suspend the generating of the supply voltage based on the RF jammer indication signal if the power level of the target received signal is above a threshold. In other aspects, the receiver bias circuit changes the supply voltage during cyclic prefix (CP) intervals between downlink intervals.
